POWER-TRANSMITTING ATTACHMENT FOR TRAGTORS.

Application led October V16, 1924. A Serial No. 743,9163.

Be it lmown that I, SYVER LIEN, a citizen of the United States, residing at Comfrey, in the county of Brown and State' of Minnesota, have invented certain new and useful Improvements in Power-Transmitting Atdeclare the following to be a full, clear,

Aand exact description of the invention, such as will enable others skilled in the art to which it appertainsl to make and use the same.

My invention has for its object to provide a'power transmitting attachment for tractois, and to this end it consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

A commercial Fordson tractor has, as a part of its standard equipment, a belt pulley attachment intended for use when the tractor is to be yused as a stationary engine and to be removed when the tractor is to be u/sed as a traction vehicle. Such an attachment includes a pulley housing having journaled therein a shaft equipped atits outer end with a pulley and at its inner endl a bevel gear adapted to mesh with the transmission shaft bevel gear of the tractor to drive said pulley. This attachment is designed to have its ulley housing, inner portion of itsl shaft an attached beveled gear inserted. transversely into the transmission housing of the tractor through an opening in the right side thereof normally closed by a foot bracket which, of course, must be removed before thel attachment can be applied. This foot bracket'has a flange which overlaps an outer flat boss which surrounds the opening in the transmission housing and in which flange Iis .a plurality of circumferentially spaced holes; through which extend machine screws that have screw-threaded engagement with said boss and detachably secure the foot bracket to the transmission housing. The pulley housin of the attachment has, at its outer end, a ange with holes which correspond to the holes in the ange of the foot bracket whereby said attachment may be secured-to the transmission hou-sing with the,

of the belt pulley attachment is materially greaterthan the distance between said hous,l ing and wheel, 1t 1sl necessary 1n order to picker, harvester or the like, while the tractor is operating as a traction vehicle. Said invention also provides such an attachment from which a machine or other device may be operated when positioned in front of the tractor, back of the tractor or at one side thereof, and While the tractor is used either as a traction vehicle vor a stationary engine. My attachment may also be applied to such a tractor or removed therefrom without removing one of the wheels, 'and a belt or tumbling rod may be driven therefrom. y

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 3 is a detail view in section showing the means for attaching the outer housing sections to the inner housing section;

Fig. 4 is a view corresponding to Fig. 1 but showing another adjustment of the invention; `v

Fig. 5 is' a rear elevation of the parts shown in Fig. 4; and

Fig. 6 is a side elevation of the same.

In the drawings the invention is .applied to a tractor having the same characteristics as a .Fordson tractor, and the fragmentary illustrated parts thereof include the right side of the transmission housing 7 rear right traction wheel 8 and transmission shaft bevel gear 9 which is provided to drive the belt pulley attachment heretofore referred to. The right side of the transmission housing 7 has an'opening l0 normally closed by a foot bracket, not shown, and in whichv opening may be mounted the belt pulley attachment which is part of the standard equipment of the tractor and to apply this attachment, as previously stated, it is necessary to remove the right wheel 8 in order to insert the attachment endwise through the opening 10 to cause its bevel gear to mesh with the bevel gear 9. The transmission housing 7 at the opening l() has an outstanding flat boss 11 in which is formed a plurality of screw-threaded holes l2 in which are mounted screw bolts 13 provided for securing 'the foot bracket, not shown, to said housing.

rIhe invention as illustrated comprises a permanent assembly A and removable assemblies B and C which are interchangeably usable with the asselnbly A. Said assembly A includes a cast open ended housing section 14 through which projects an inner shaft section 15 journaled in ball bearings 16 in the open ends of said housing. (ln the outer end of the housing section 14 is an annular flange 17 which overlaps the boss 1l and is permanently secured to the transmission housing 7 by the screws 13 which project, through countersunk holes in said flange. Inward of the flange 17, the housing section 14 is provided with an annular shoulder 18 which is telescoped into the opening 1() and securely holds said housing properly aligned and against lateral movement. It may be here stated that there is sufficient clearance, between the transmission housing 7 and wheel 8 to insert the housing section 14 through the opening 10 and secure the same in position by the screw bolts 13. i On the inner ed of the shaft section 15 is a bevel gear 119 which meshes with the bevel gear 9 and drives said shaft section 15 therefrom. Said shaft section 15, outward of the housing 14, has a tapered outer end 20 and a screw-threaded reduced stud 21 to which is applied a nut 22.

The assembly B comprises an open ended case housing section 23 through which projects an outer shaft section 24 axially aligned with the shaft section 15 and which shaft section 24 is journaled in front and rear ball Abearings 25. Outward of the outer bearing 25 is a felt oil retainer 26 held in position by a cover plate 27. Keyed to the outer end of the outer shaft section 24 is a pulley 28. On the inner end of the outer shaft section 24 is a separable coupling comprising a disc-like member 29 and a cuplike member 30, the former of which is permanently secured to the outer shaft section 24 and has a plurality of radial lugs 31 mounted in notch-like seats 32 formed 1n the rim of said cup-like member. The cuplike member 30 has an axial hub 33 that isremovably telescoped onto the tapered end 20 of the inner shaft section 15, held for rotation by a key 34 and against axial removal from said tapered end by the nut 22.

Formed with the inner end of the housing section 23 is an outstanding annular flange 35 which overlapsthe flange 17 and is detachably secured thereto by a plurality of machine screws 3G. Inward of the flange 35 the outer shaft section 15 is provided with a short extension 37 which telescopes into a shallow recess 3S in the outer face of the flange 17 and securely holds said housing section in its proper relation with the housing section lo so that the outer shaft section 24 is in axial alignment with the inner shaft section l5. ln attaching the assembly B to the assembly the separable coupling member 3l) is first secured to the inner shaft section l5 and then the outer housing section 23 is secured to the housing section 14 by the machine screw 36 after the assembly has been moved axially endwise to cause the separable coupling member 29 to interlock with the separable coupling member Il() and to telescope the extension 37 into the recess 3H. Obviously, this axial movement of the assembly B is very slight and the distance between the wheel 8 and the flange 17 is sufficient to permit this movement of the assembly B. i

The assembly l includes a cast. housing section 39 the inner side ofv which is open, as well as the top and which top is normally closed by a cover plate 4l) held in position by machine screws 41. An outer-shaft section 42 extends completely through the housing section 39 from the front to the rear thereof and at right angles to the inner shaft section I5. .lhis outer shaft section 42 is journaled in roller bearings 43 mounted in the front and back of the housing section 39 and the openings in the front and back'of the housing section 39 are normally closed by cover plates 44 held in osition by machine screws 45 and having elt oil retainers 4G. Keyed to one of the projecting ends of the outer shaft section 42 is a pulley 47 and to the other projecting end thereof is attached a tumbling rod 48. Keyed to the outer shaft section 42 within the housing section 39 is a bevel gear 49 which meshes with a bevel pinion 50 secured on the tapered end 2() of the inner shaft section 15 by the nut 22 and key 34 in place of the separable connection member 30.

The housing section 39, at its inner end, has formed therewith an annular outstanding flange 5l detachably secured to the flange i-,aanerra 'chine or device` positionedeitherforward or` backward ofl the" tractor may' be operated. by

means; of the tumbling rod 48. It should be here stated that the: shaft42 may be removed form the housing; sectiom'39 and; its gear removed1 therefrom turned end vfor end, andv again replaced in th ythe gear 49V a ain t e housinsection 39 and reto. It will thus be seen t at the direction olf rotation. of the outer shaft section42 may be reversed andthe 481 positioned to extend either forward or rearward of the tractor.

i This assembly C', like'aembl B, requires only 'a s1 ght; axial movement uring its application to formed'therewith a half clutch, 53 arranged for co-operation with a half clutch 54 formed with the hub of a shi per collar4 55 onthe shaft 42. Said .tumbing rod u48 is held against axial movement on the shaft 42 by a set screw 56 which extends into a circumferential channel 57 in the shaft 42 but permits free rotation of said shaft in the tumbling rod 48. The shipper collar 55 is secured to the shaft 42 for rotation therewith v by a key 58 arranged to' permit fr ee sliding movement of said collar. The shipper collar 55 is moved on the shaft 42 -to slide the Half clutch 54 into and out'of'engagement with the` half clutch 53 by a shipper lever 59 mounted on a bracket 60 secured to the respective cover plate 44 by the attaching screws 45.
